Not able to install composer in laravel project

Question

I am new in Php and start working on laravel based project but facing one issue when installing composer on project level (I am using Phpstrom Ide).

composer install --no-interaction --ansi Loading composer repositories with package information Installing dependencies (including require-dev) from lock file Nothing to install or update Generating optimized autoload files > Illuminate\Foundation\ComposerScripts::postInstall > php artisan optimize Script php artisan optimize handling the post-install-cmd event returned with error code 1 Failed to install packages for ./composer.json.

Process :-

Hit this command in order to create laravel project

composer create-project laravel/laravel --prefer-dist

and project is created with this error and no vendor folder is created

Installing laravel/laravel (v5.4.30) - Installing laravel/laravel (v5.4.30): Downloading (100%) Created project in C:\wamp64\www\laravel

php -r "file_exists('.env') || copy('.env.example', '.env');" Script php -r "file_exists('.env') || copy('.env.example', '.env');" handling th e post-root-package-install event returned with error code 1

Hello, can you provide more details like the project folder content? — Renoir Reis
@RenoirReis I updated my question with process Which I followed in project creation. — Nishant Dixit
@RenoirReis I updated composer -v and composer -version output — Nishant Dixit
Your php.ini appears to have D:\mysql\temp as the setting for sys_temp_dir. Composer is complaining that it does not have access to that directory or the directory does not exist. — RyanNerd

[Symfony\Component\Console\Exception\RuntimeException] The "-e" option does not exist.

Above error comes because of options shortcuts… here composer - version means composer -v… and which is not working in your case. That's the reason behind the last error stack.

Refer this link to see GitHub issue. the -e option does not exist

instead of running composer -version try to run

composer --version

and see it shows composer version or not...if not then the composer is not installed properly.

Then run

laravel --version

if you don't see version there. install composer and laravel again. Below link will be helpful for step by step installation.
